Cup or UEFA Cup Winners' Cup could not continue games in other European competitions after the end of the summer break. This meant that clubs who had progressed from the Intertoto Group Stage, but were also competing in one of the UEFA competitions, had to be given byes through the Intertoto knock-out rounds (until they were eliminated from the UEFA competition), or withdrawn entirely. This made the knock-out rounds complicated, difficult to schedule, and weakened their significance. The third reason was the lack of value attributed to the knock-out rounds. While reaching the final was seen as an achievement worthy of praise, the main purpose of the tournament, for most clubs who entered, was to provide football during the otherwise empty summer break. The financial benefits of participating in the pools competitions was also important. Having to arrange and play home-and-away knock-out matches during the new season was seen as difficult, expensive, and relatively pointless if the club in question was eliminated before reaching the Final or Semi-finals. As a result, the knock-out rounds were abandoned, and for the next three decades there were no winners of the cup. The Group Stage continued much as before, with prize money still awarded according to a club's final group placing.
